In satellite communication, the uplink frequency is higher than the downlink frequency because the attenuation level increase with an increase in frequency . The power at the ground station (Base Station) is more than compared to the power available at the satellite.
Read moreWhy must a satellite have distinct uplink and downlink frequencies?
In order to avoid interference , the satellite must have distinct uplink and downlink frequencies. The satellite receives the signal on one frequency and it transmits on another frequency, the reason is to avoid the interference of signals. … To obtain clear transmission, the frequency must be distinct between them.
